Troubleshooting

My transactions are not getting confirmed

You need to make sure that your node is well connected - it is suggested that you have around 7 neighbours. Check that all of your neighbors are successfully sending you transactions. If they are not, it is possible that they did not add you as a neighbour or are not currently online.

I have replayed a transaction and it still does not confirm

First check that you are properly synced to the latest solid subtangle milestone and have good connectivity to your neighbours.

Transactions currently have a period of 9 milestones to enter the tangle; after this time they will never get confirmed. If you have tried to replay 3 times (each time waiting for 9 milestones) and it still has not confirmed, you should send a fresh transaction.

You can also check that the transaction you have sent is a double spend. Click "show bundle" and look for the address with negative sign in front. Use the getBalances command in Console (http://188.138.57.93/console.html) for this address:

If you get zero as an answer then your transaction was a double spend and will never confirm.

How can I claim my IOTA with an old Seed?

If your Seed contains special characters (such as #[email protected] etc.) and is not comprised of only capital letters and the number 9, then you probably have an old Seed.

Follow our claim tutorial, but use the following method to modify your old Seed: change all lower case letters to their capital letter equivalent. Second, change all of the special characters to “9”.

After replacing my database, some balance/addresses are missing. What can I do?

Do not worry, it is extremely likely that your IOTA are safe! In order to get the balance back, generate new addresses (as many as there went missing). Your missing balance will then appear again.

When you replace your database, all addresses that were ‘confirmed = false’ will disappear, as addresses that are unconfirmed are only stored locally on your node. This is the cause of the missing balance.

There are a lot false tx coming into my terminal. What can I do?

If you see the following error message then you need to update to the latest version.
